[issue34990] year 2038 problem in compileall.py

[Bernhard M. Wiedemann]

New submission from Bernhard M. Wiedemann <pythonbugs at lsmod.de>:

To reproduce:
touch -d 2038-01-20 /usr/lib/python3.6/site-packages/six.py
python3 /usr/lib64/python3.6/compileall.py


  File "/usr/lib64/python3.6/compileall.py", line 198, in compile_path
    legacy=legacy, optimize=optimize)
  File "/usr/lib64/python3.6/compileall.py", line 90, in compile_dir
    legacy, optimize):
  File "/usr/lib64/python3.6/compileall.py", line 138, in compile_file
    mtime)
struct.error: 'l' format requires -2147483648 <= number <= 2147483647

It could use either 
64 bit int (requires new .pyc format with different magic number) or
unsigned 32 bit int (gives us only another 68 years)
